Guide 4 Homeostasis Objectives

This guide’s quiz has four questions; one matching each objective.

Urinary System

Describe the properties of water that make it a critical molecule for life as we know it; provide examples of ways humans take in and lose water, including the various components of blood plasma; and list the urinary organs and state the function(s) of each organ.

Urinary Disorders

Describe the types of information provided by urinalysis, including some of the limitations of trying to make diagnoses simply based on urine characteristic; list and describe various kidney diseases, including kidney stones, renal cancer, polycystic disease, and urinary tract infections; and describe liver functions and diseases, including the impact of excessive alcohol consumption.

Endocrine System

Locate various endocrine organs in the body. Explain how the nervous system and endocrine system connect, why this is important, and the hormones produced by the pituitary. Describe what hormones are and list the hormones produced by various endocrine organs.

Stress & Metabolism

Explain what stress is, including examples of short-term and long-term stress events; describe the impacts of adrenaline (epinephrine) and cortisol on the body and list factors that can reduce the potential impacts of a stress response; and define metabolism, including catabolism and anabolism and explain how hormones impact appetite.

Journal Assignment #7

Introduced in the Endocrine System section of this guide:

Journal Page #7: Homeostasis Analogy

An analogy is a comparison of two otherwise unlike things to explain or clarify a concept. Analogies are frequently used in science education to teach challenging concepts. Doctors frequently use analogies to explain medical conditions to a patient: The heart is a pump; the kidneys are like filters; vaccines are weapons in our arsenal; a treatment is on target.

For this journal page you are developing your own analogy that represents homeostasis in the human body. You can brainstorm and/or scan the web for ideas, and then develop the analogy further for this assignment.

Your analogy is intended to teach homeostasis to someone who is not familiar with the concept. You can tell a story, draw a comic strip, or make some other representation of your homeostasis analogy.

You are turning in:

A representation of your homeostasis analogy (story, comic strip, drawing, etc.).
An explanation of your analogy that clearly depicts how the analogy explains/clarifies the homeostasis concept.

Journal Assignment #8

Introduced in the Stress & Metabolism section of this guide:

Journal Page #8: Stress Study

For this journal page, you are designing a mini study of your own stress. This can be qualitative (finding variables) or quantitative (testing variables). You are designing this mini study and turning in your procedure.

You do not need to conduct this min-study, but if you do, exercise care and safety in all self-study procedures.

Possible examples of self-study of your own stress:

Take an online stress survey and reflect on the results, as well as critiquing the quality of the survey.
Try different activities and reflect on your perception of time during each activity.
Monitor heart rate at different times of day related to different activities that may be stressful, including things like studying, Zooming a class, etc.
Collect different people’s ideas about stress and write about how your most stressful events compare to other people’s events.
Develop a space intended to reduce stressful triggers and monitor your response.

What you are turning in a summary of your mini-study that includes:

your procedure, including whether it is qualitative or quantitative.
why you chose this form of data collection.

Sometimes reflecting on stress can reveal concerns that were otherwise hidden. If you need assistance with stress management or simply a professional to weigh in, OSU’s CAPS program is available to all enrolled students.

Journal Page Directions

To be completed after taking the quiz on Canvas.

Upload your two journal pages to Canvas. If the files are really large, it may help to host it on a webpage and submit the web link to reduce upload time.

All three assignments are due by Fiday 11:59 p.m. P.T. Once you have taken the quiz on Canvas and uploaded your two journal pages, you have completed this guide.
